Farim fire, 3 March 2026 Farim

Out · last detection 15 Mar 2026, 14:18 UTC

The fire started on 3 March 2026 in Farim, Guinea-Bissau, and satellites saw it burning for 13 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,806 hectares from heat detections, spread across a single municipality.

It is the 3th largest in Oio since 2016 (of 58 with a page). Number 2 in Guinea-Bissau in 2026, of 75.

The power measured by the satellite is low (21.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

54% of the perimeter overlaps earlier fires recorded since 2016: 88 ha in 2016, 80 ha in 2019, 890 ha in 2021, 619 ha in 2022, 867 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 2,072 ha that had burned before.

Frequently asked questions

How long did the Farim fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 3 March 2026 to 15 March 2026 (13 days). The perimeter dates it from 5 March 2026 to 12 March 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,806 hectares (38.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Farim (3,829 ha, 2.4 %).
What was the weather like?
During the fire the temperature reached 40.8 °C, humidity dropped to 13 % and gusts hit 41 km/h. The fire danger index (FWI) reached 56, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Guinea-Bissau (geoBoundaries). It is not an official report.

Where to verify it

A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Satellite cross-check

Does something look wrong on this page?

This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

Where this data comes from

The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Open Data Commons Open Database License 1.0). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
